Paper vs Digital Flashcards: Which Should You Use?

Across six vocabulary studies, neither medium won overall. In three, college students did about as well with paper flashcards as with digital ones, though computer cards lagged in one. Digital cards pulled ahead for lower-proficiency university learners of English and for children learning Chinese words with audio. So choose by what your cards must carry and which you will review.

That answer draws on the six studies’ published abstracts. Three, by psychologist Kara Sage and colleagues, compare paper and digital cards with college students. The other three test second-language vocabulary, and two of them report a digital advantage for particular learners.

Are paper flashcards better than digital flashcards?

In the three Sage studies, paper and digital cards mostly produced similar learning, with one exception. The first, Pacing, Pixels, and Paper (2016), had college students learn vocabulary from paper flashcards or from one of four digital slideshows, ranging from fully automatic to fully self-paced. The abstract reports: “Users reported feeling more in control when indeed having some control, but ultimately memory recall, cognitive load, and satisfaction were similar across the five versions.”

From that, the authors suggest “that paper and digital flashcards are equally viable options for students.” They also observed: “Notably, whether paper or digital, students showed individual variability in how they advanced through the words.”

The second study, Flip, Slide, or Swipe? (2019), holds the exception. College students learned vocabulary from paper, computer or tablet flashcards that they had either made themselves or received ready-made. The abstract reports: “Results showed that students learned equally well from paper and tablet but less well from computer flashcards.” It adds: “They were less satisfied with, and felt less in control of, computer-based flashcards.”

The third, Flip It or Click It (2020), randomly assigned college students to paper, laptop or smartphone flashcards and found their learning equivalent across the three. The exception the abstract names is time: “students spent longer reviewing paper flashcards.” It also reports: “Self-reported cognitive load and satisfaction were equal across platforms.”

So a laptop matched paper in 2020, while a computer lagged behind it in 2019. The two results differ for computers, and neither abstract explains the difference. The 2019 paper, again led by Sage, repeated the 2016 conclusion and added a condition: “This research suggests that paper and digital flashcards are equally viable options for students but platform matters.”

Are handwritten flashcards better than digital ones?

None of the six abstracts reports a comparison of handwritten cards with typed ones. The nearest result is from the 2019 Sage study, where students recalled more words from the ready-made cards than from the cards they had made themselves. The abstract does not say whether the self-made paper cards were handwritten, and it reports no result split by platform and card type, so the finding says nothing about handwriting as such.

Treat it as one vocabulary study, and as a caution against assuming that writing a deck is where the learning happens. If making cards helps you work out what each one should ask, keep making them, and give the reviews that follow at least as much of your time.

Notes are a different task. Our comparison of handwriting vs typing notes finds a modest edge for the pen, which it credits to slowness forcing you to condense ideas into your own words. Reviewing a finished card asks you to retrieve the answer on its back.

When did digital flashcards pull ahead?

Two studies of language learners found a digital advantage for particular groups. In a 2018 study of 139 Japanese university students, Ashcroft, Cvitkovic and Praver had every participant study words from the Academic Word List with both digital and paper flashcards. The abstract reports that students “of lower levels of English proficiency have significantly higher vocabulary learning gains when using digital flashcards than when using paper flashcards.” At the other end of the scale: “Students at higher levels of proficiency performed equally well using both study modes.”

The authors offer a hedged explanation: “It appears that” digital cards, by compensating for gaps in metacognitive awareness and learning strategies, “may provide the additional support lower-level learners need” to keep pace with advanced peers.

In a 2019 study by Li and Tong, 100 English-speaking fourth and fifth graders learned 20 new Chinese words, half from e-flashcards on iPads and half from paper cards. The e-flashcards added audio to the visual and verbal inputs the paper cards gave. Children using them “statistically outperformed those who used paper flashcards on immediate post-tests of Chinese word reading and listening, as well as on 1-week delayed listening test.” The delayed advantage reported is for listening. The authors read their results as support for “the audio application of multimedia on Chinese word recognition among novice Chinese language learners”.

A paper card cannot play a sound, so if pronunciation is part of what you are learning, that is a strong reason to go digital, or at least to pair paper cards with recordings you play separately. Our roundup of flashcard apps for language learning compares which apps can speak a card or play a recording you add.

Does how you use paper flashcards change the result?

One study suggests it can. Dizon and Tang (2017) note that several earlier comparisons had concluded digital flashcards were more effective, and point out that those studies “did not utilize vocabulary learning strategies (VLSs) as a way to support the vocabulary development of those using PFs.” PFs are paper flashcards, and DFs, below, are digital ones.

In their 12-week study at two Japanese universities, 52 students of English as a foreign language used either paper flashcards with three strategies (dropping, association and oral rehearsal) or the digital tools Quizlet and Cram. “Results from a paired t-test revealed that both groups made significant improvements in receptive and productive vocabulary.” The gap between the groups was not significant, which, in the authors’ words, “contrasts with past comparison studies of DFs and PFs and highlights the importance of VLSs.”

One reading is that how you use paper cards may close a gap that earlier studies reported. The strategies came bundled with the paper cards, so the study cannot say how much of the result belongs to them.

Do students prefer paper or digital flashcards?

Preference was not consistent across these studies. The 2019 Sage abstract reports: “Students also felt more satisfied with paper than either digital card set.” Dizon and Tang report the opposite lean, “indicating that the students viewed DFs more favorably than PFs.” The 2016 and 2020 Sage studies found satisfaction similar across the versions they tested.

The 2019 abstract makes the point directly: “Furthermore, perceptions matter.” We read that as permission to count your own preference. When two media teach about equally well, a deck you like opening is probably one you will open more often. Satisfaction also went with results in two of these studies. In 2016, memory recall was positively related to satisfaction with the flashcard set, and the 2019 authors found satisfaction meaningfully related to performance, though neither abstract shows which causes which.

How do you choose between paper and digital flashcards?

With neither medium ahead across these studies, start from what your cards need to carry. The table is our own mapping. Its first row draws on the Li and Tong result, and the rest are practical differences that none of the six abstracts reports measuring.

On scheduling, the Leitner box system runs spaced reviews on paper with a few boxes, and a spaced-repetition app such as Anki automates the same logic, so that choice comes down to convenience and habit. A paper system and a scheduling app are the same idea at two levels of automation, and our guide to building a spaced repetition schedule sets out intervals that work with either.

Two last checks. If your level in the language you are studying is still low, digital cards deserve a trial, since Ashcroft and colleagues found that lower-proficiency university students of English gained more vocabulary from digital cards than from paper ones. Otherwise, pick the medium you will open most days.

What makes either kind of flashcard work?

The habits carry across media. Answer from memory before you flip, space your reviews over days, keep one idea per card, write it in your own words, and grade yourself honestly. Our guide on how to use flashcards effectively goes through each one.

What do these studies leave open?

All six are vocabulary studies: five with college students and one with children. Nothing above reports a method detail or a result beyond what the abstracts and titles state. Whether the same patterns hold for chemistry mechanisms, history dates or anatomy labels is a question these studies were not built to answer.

Where GeniusPal fits

GeniusPal sits on the digital side of this choice. It turns an uploaded file (a PDF, Word, PowerPoint, plain text, Markdown or CSV file of up to 10 MB) or a pasted link into a study set of questions. On the Free plan, that set is a multiple-choice quiz. Flashcard mode, recall mode and written quiz answers come with the paid Student and Genius plans.

It does not schedule reviews and sets no due dates. The daily review, free on every plan, is built from questions you missed or have not yet mastered. It cannot read photos or image-only scans either: an image file is refused, and so is a scanned PDF with no text layer, so it will not turn a handwritten deck into a digital one. If your notes are typed, it can turn them into digital practice questions, and your paper cards can keep their place beside it.
